rop - response object proxy

Have you ever had a problem, where you refactor java objects, and accidentally end up breaking your API because it refactored all the tests? Rop will eliminate this possibility by wrapping testable objects. Forcing the developer to use object field comparison with String literal.

Usage

Setup gradle

Do note that both TestNG and Junit are included by default. Make sure to exclude them if you already have the dependencies.

repositories {
    jcenter()
}
dependencies {
    testCompile('com.snyberichapp.tools:response-object-proxy:1.0.2') {
        exclude module: 'junit'  // exclude if needed
        exclude module: 'testng' // exclude if needed
    }
}

Setup TestNg

// Second parameter defines consumer for printAssertions
Rop.setConfiguration(new TestngConfiguration(), System.out::println);

Setup Junit

// Second parameter defines consumer for printAssertions
Rop.setConfiguration(new JunitConfiguration(), System.out::println);

Basic

Car car = new Car();
car.setMake("Audi");
car.setModel("A7");
car.setYear(2017);
car.setNotes(Arrays.asList("Good condition", "Low mileage");
Rop.of(car)
    .assertEquals("make", "Audi")
    .assertEquals("model", "A7")
    .assertEquals("year", "2017")
    .assertEquals("notes[0]", "Good condition")
    .assertEquals("notes[1]", "Low mileage")
    .assertArraySize("notes", 2);

Separate elements logically

List<String> elements = Arrays.asList(
    "int",
    "double",
    "short",
    "String",
    "Object"
);
Rop.of(elements)
    .assertEquals("[0]", "int")
    .assertEquals("[1]", "double")
    .assertEquals("[2]", "short")
    .separator()
    .assertEquals("[3]", "String")
    .assertEquals("[4]", "Object")
    .separator()
    .assertArraySize(5);

Assert the whole object

Make sure to call assertAll() in the end, otherwise it won't fail for invalid assertions.

Rop.of(car).enableAssertAll()
    .assertNotNull("make")
    .assertStartsWith("model", "Volks")
    .assertContains("year", "1783")
    .assertAll();

Print all object data

Rop.of(car).printAssertions();
